STITCH SEPARATING OR INDENTING TOOL.

Specification of Letters Patent.

Patented Dec. 15, 1908.

Application flled June 6, 1904. Serial No. 211,237.

In the manufacture of shoes it is Gus-- tomary to form a series of transverse indentations along the'upper surface of the projecting sole edge'to give a pleasing and finished appearance to' the shoe, these indentations being in efl'ect impression or imitation stitches and serving either to bring into prominence the stitches of the outseam, when the shoe is provided with an outseam, 01' when the shoe is not provided with an outsealn, giving it the appearance of a stitched shoe.

In indenting the sole of a shoe provided' with an outseani the stitches of which appear on the upper surface of the sole the indentations are fornied in the st-itch intervals being spaced apart distances corresponding to the lengths of the stitches and preferably the crowns of the stitches and the leather between the indentations are roundedy over or pressed into a predetermined Shape. The tool which is usually employed in indenting the stitch intervals of an outseam and in Shaping the crowns of the stitches is provided with a groove of the Shape which it is desired to impart to the crowns of the stitches, and this tool before being pressed into the work to indent .and shape each the stitch or in one of the stitch intervals. In Operating upon the sole of a shoe which is not provided with an outseam or in which the outseam is' covered by a channel tlap, a grooved wheel is usually ernployed, the grooves of which are spaced at regular intervals around the periphery of the wheel.

and shaped to give the required Shape to the indentations.

In se arating and indenting t-he stitches of a finished seam or in indenting the surface of a sole which is not providedwith a seam, it is necessary, on account of the tend- 'ency of the leathe'r to return to its original inarrino" position, to force the tool into the work a suflicient distance to bring the working face of the tool below the surface of the work. lVhen the tool is so pressed into the work the outer end of the tool cuts into the work so that the work is inarred by a line extending along the surface near the upper at the ends of the indentations. n Operating on welted shoes the outer end of the tool acts upon the welt close to the inseam and onA account of the great pressure exerted upon the welt at thiscpoint, tends to weaken the seam andv tear the welt from the upper.

The object of the present invention is to remedy this defect in the operation of tools which are used either to separate and indent the stitches of a. finished seam or to indent the edge of a sole which is not provided with an outseam and with this object in view the invention coutemplatesthe provision of a stitch indenting tool having a grooved working face which curves upwardly at its outer end. By curving the working face of the tool upwardly at its outer end, this portion of the working face is prevented from the work when the-remaining portion is forced below the surface of the work, as no sharp Cutting edge is formed at the outer end of the tool, as` in tools which have heretofore been used, which can cut into and mar the surface of the work. Also the tool can be used to form indentations on welted work extending close to the inseani without liability of tearing the Welt from the upper.

The invention/'may be einbodied in any form of tool adapted for operation either upon a sole provided with a finished seam or upon a sole in which no stitches appear upon the upper surface.

The invention will be clearly understood from an inspection of 'the Yi'accompanying drawings in which Figure 1 is a view in front. elevation of a stitch separating and indenting tool' embodying the same, Fig. 2 is a view in side elevation of the tool illustrated in Fig. 1, and Fig. 3 is. a longitudinal sectional view thereof, Fig. t is a view in end elevation of an indenting wheel embodying' the invention, Fig. 5 is a sectional view thercof taken ou the line 5-5 and Fig. 6 is a sectional view illustrating the tool shown in Figs. '1, 2 and 3 forccd into the upper surface ofthe projecting edge of the sole of a welted shoe.

The tool illustrated in Figs. 1, 2 and 3 is provided With two stitch sepamting and indenting blades 1 and 2 and With a groove 3 between the indenting blades, the surface of which is shaped to `give the desired `Shape to the Crown of the stitch. 'This surface constituteewhat may be terrned the Working face of the tool. In accoi'dance with the present invention this surface is Curved upwardly at atthe outer end of the tool so that the poi'tion of the Working face at the outer end of the tool is somewhat higher than the i'emaining portion. rl`he result secui'ed by curving the face of the tool up- Wardlf,T at its outei' end will be appai'ent from an inspeetion of Fig. (i in which it Will be seen that When the tool is fi' L'ced into the Work so as to bring the main poi'tion of [iiinlr'ei'itifiaigg; :hub .ili/'iimilf:v :111 '1 i "ma mir'd romitiiim Was:
